Last month I published a post in regards to the Dell VRTX, ESXi 5.5, and storage – or the lack thereof. Well shortly after publishing that article Dell announced full support for ESXi 5.5 and released an ESXi 5.5 image on their website for those looking to upgrade or install. In the chance that my little driver work around might affect support I decided I’d better pull the image down and get it installed on the few VRTX’s I had already deployed.
That said, looking at the build numbers and attempting to not have to redo all of the configuration I had already applied, I decided to take the upgrade route – even though the only difference was most likely the storage driver. The upgrade process itself went smooth – no issues, no problems. But after it was complete guess what was missing? Yup, the datastore was gone again!
Now this wasn’t the same issue of missing storage that I described the last post. Previously I couldn’t see the storage at all, this time, when looking at my Storage Adapters I could actually see the device that hosted my datastore listed. So it was off to the CLI to see if I could get a little more information about what was going on.
To the CLI Batman!
After doing some poking around I discovered that the volume was being detected as a snapshot/replica. Why did this happen? I have no idea – maybe its the fact that I was messing around with the storage drivers 🙂 I guess that’s why they say things are supported and unsupported 🙂 Either way, how I found this out was with the following command.
esxcli storage vmfs snapshot list
This command actually displayed the volume that I was looking for, and more specifically showed that it was mountable. So my next step was to actually mount that volume again. Take caution here if you are doing the same. I know for sure that this volume is the actual volume I’m looking for – but if you have an environment with lots of lun snapshots/replica’s you will want to ensure that you never mount duplicate volumes with the same signature – strange things can happen. Anyways, to mount the volume, take note of the VMFS UUID and we can use the following command.
esxcli storage vmfs snapshot mount -u 5315e865-0263a58f-413a-18a99b8c1ace
And with that you should now have your Dell VRTX storage back online – everyone is happy and getting along once again – Thanks for reading!
